Vladimir Naumovich Gribov (Russian Влади́мир Нау́мович Гри́бов; March 25, 1930August 13, 1997) was a prominent Russian theoretical physicist, who worked on high-energy physics, quantum field theory and the Regge theory o ...
, laying a basis for a field theory description of deep inelastic scattering
In particle physics, deep inelastic scattering is the name given to a process used to probe the insides of hadrons (particularly the baryons, such as protons and neutrons), using electrons, muons and neutrinos. It was first attempted in the 196 ...
and annihilation (Gribov-Lipatov evolution equations, later known as DGLAP
The Dokshitzer–Gribov–Lipatov–Altarelli–Parisi (DGLAP) evolution equations are equations in QCD describing the variation of parton distribution functions with varying energy scales. Experimentally observed scaling violation in deep inelast ...
, 1972). He wrote significant papers of the Pomeranchuk singularity in quantum chromodynamics
In theoretical physics, quantum chromodynamics (QCD) is the study of the strong interaction between quarks mediated by gluons. Quarks are fundamental particles that make up composite hadrons such as the proton, neutron and pion. QCD is a type of ...

In physics, a renormalon (a term suggested by 't Hooft) is a particular source of divergence seen in perturbative approximations to quantum field theories (QFT). When a formally divergent series in a QFT is summed using Borel summation, the assoc ...
